Abstract
An improved means for venting building attics has an opening along the peak of a roof, and cap shingles are spaced from the underlying roof portions by an elongated, relatively thin vent. The vent comprises a matting, or matrix of randomly convoluted polymeric filaments heat bonded to a porous, sheet material layer. The sheet material layer overlies the peak opening and is wrapped around the edges of the filament matrix, to prevent entry of foreign material into the matrix, as well as into the attic, while permitting flow of ventilating air, through the peak opening and outwardly beneath the cap shingles.
